MIXING DEVICE.

Application filed August To all whom it may concern:

Be it known that I, HARRY A. VAN VLEGK, a citizen of the United States,residing at Parsons, in the county of Labette and State of Kansas, haveinvented new and useful Improvements in Mixing Devices, of which thefollowing is a specification.

This invention relates to attachments for internal combustion engines,particularly to mixing devices, and has for its object the provision ofa device adapted to be interposed between a carbureter and the intakemanifold of an engine whereby to break up the gasoline vapor and therebyrender it more highly explosive and consequently more efiicient as afuel.

An important and more specific object is the provision of a device ofthis character which is formed as a gasket adapted to be clamped betweenthe flanged meeting ends of the ca'rbureter and intake manifold, thegasket carrying a fine wire screen of peculiar shape through which thegasoline vapor passes and by means of which the vapor is broken up and amore intimate commingling of the gasoline vapor and air effected.

An additional object is the provision of a device of this characterwhich will be simple and inexpensive in manufacture, highly efiicient inuse, durable in service, and a general improvement in the art. With theabove and other objects and advantages in view, the invention consistsin the details of construction to be hereinafter more fully describedand claimed and illustrated in the accompanying drawings in which Figure1 is an elevation of my device,

Figure 2 is a longitudinal sectional view therethrough, and

Figure 3 is a cross sectional view.

Referring more particularly to the draw ings, I have shown my device ascomprising a pair of gaskets of a size and shape to fit between theflanged ends of a carburetor and intake manifold, the ends of thegaskets being formed with holes 11 for the passage of the usual bolts,not shown, employed for holding the flanged ends together. These gasketsare of course provided with openings 12 at their centers for the passageof the mixture, Disposed between the two gaskets is a circular piece ofwire screen 13 which s 0? sstead t the outer e es of 2, 1921. Serial No.489,325.

the gaskets and the gaskets are cemented or otherwise secured togetheroutwardly of the edge of the screen 13. WVithin the openings 12 theportion of the screen 13 exposed is peculiarly formed. At this point thescreen is pressed into angular shape, as shown, whereby it will beV-shaped in cross section with the vertex of the V formed as a ridge 14which faces toward the current of I111??- ture. This pressing of thescreen results in providing inclined surfaces 15 which of course divergefrom the ridge 1%.

When my device is inserted between the carbureter and intake manifold ofthe en gine it is apparent that when the current of mixture strikesagainst the screen it will be most efficiently broken up, the gasolinebeing more intimately commingled with the air whereby a more explosivefuel will be provided which will greatly improve the runnmg of theengine. This V-shaped screen does away with the use of all splittingbars or anything else that might be placed in the center of thevaporizer to break and spread the gas.

Having thus described my invention. I claim:

1. A device of the character described comprising a gasket adapted to besecured between the flanged meeting ends of the carburetor and theintake manifold, the gasket being provided with a central opening forthe passage of fuel mixture therethrough, and. a wire screen carried bythe gasket and having its portion covering the opening pressed outwhereby to be Vshaped 1n cross section with the vertex of the V facingtoward the stream of mixture.

2. A mixing device adapted for interpositlon between the flanged meetingends of a carbureter and the intake manifold comprlsing a pair ofgaskets provided with rep;- istering holes for the passage of securiiigbolts and provided with registering central openings, and a sheet ofwire sc-reen disposed between the gaskets and covering said opening, theportion of the gauze exposed at. the opening being pressed into angularshape with the vertex formed as a ridge to define diverging inclinedportions, the ridge being designed to be disposed toward the current ofmixture passing through the device.

In testimony whereof I affix my signature.

VAN VLEGK.
